Use vocab-runtime jsonld subpath

Move the jsonld ESM shim into @fedify/vocab-runtime and expose it
through the new jsonld subpath export. This avoids fragile relative
imports in generated vocab sources while keeping JSR-safe packaging for
the deep jsonld ESM entrypoint. Update Fedify's Linked Data signature
code, the vocab code generator, snapshots, and CHANGES.md to use the
shared runtime module.

 ### @fedify/fedify
 
- -  Switched Fedify's JSR-facing JSON-LD imports to jsonld's ESM entrypoint
-    so source-based runtimes such as Deno, Cloudflare Workers, and Fresh 2's
-    Vite SSR pipeline do not have to evaluate the package through CommonJS
-    interop when loading Linked Data signature support.  Fresh 2 development
-    mode has been verified on Deno 2.7.7 after an upstream Deno 2.7.6 dev
-    server regression was fixed.  [[#621], [#639]]
+ -  Switched Fedify's source-based JSON-LD loading to the new
+    `@fedify/vocab-runtime/jsonld` subpath so generated vocabulary code and
+    Linked Data signature support no longer have to evaluate `jsonld` through
+    a CommonJS-sensitive package root in Fresh 2, Deno, and other ESM-first
+    runtimes.  Fresh 2 development mode has been verified on Deno 2.7.7
+    after an upstream Deno 2.7.6 dev server regression was fixed.
